San Diego –  Coronado Bridge . . “- history of this icon of San Diego:  principal architect: Robert Mosher. Construction on the San Diego–Coronado Bay Bridge started in February 1967. The bridge required 20,000 tons of steel (13,000 tons in structural steel and 7,000 in reinforcing steel) and 94,000 cubic yards of concrete. To add the concrete girders, 900,000 cubic yards of fill was dredged and the caissons for the towers were drilled and blasted 100 feet into the bed of the bay.”  text source:  California Department of Transportation
